Problem 13E
Assume that a policyholder is four times more likely to file exactly two claims as to file exactly three claims. Assume also that the number X of claims of this policyholder is Poisson. Determine the expectation E(X2).
ANSWER:
Answer :
Step 1 of 3 :
We have to assume that a policyholder is four times more likely to file exactly two claims as to file exactly three times. And also that the number X of claims of this policyholder is poisson.
The claim is to determine the E()
We have, P(x = 2) = 4P(x = 3)
X~poisson distribution
P(X=x) =
From the equation P(x = 2) = 4P(x = 3)
We get,
=
=
=
= 3
